Question

10. Physical Science Ski resorts require large amounts of water in order to make snow. Snowman Ski Area in Colorado plans to pump at least 1120 gallons of water per minute for at least 12 hours a day from Snowman Creek between mid-October and Late December. Environmentalists are concerned about the effects on the ecosystem. Find the minimum amount of water pumped in 30 days. Let y be the total number of gallons pumped x days after pumping begins.

Answer 1

Answer:

Minimum number of gallons pumped after 30 days = 24,192,000 gallons

Explanations:

The minimum amount of water pumped in 1 minute = 1120 gallons

The minimum number of hours used for pumping per day = 12 hours

Number of minutes in 1 hour = 60 minutes

Number of minutes in 12 hours = 12 x 60 = 720 minutes

The minimum amount of water pumped per day = 1120 x 720

The minimum amount of water pumped per day = 806400 gallons

Let the number of days used for pumping be x

Let the total number of gallons pumped x days after pumping begins = y

Since 806400 gallons is pumped per day:

y = 806400x

Minimum number of gallons pumped after 30 days, that is, x = 30

y = 806400 (30)

y = 24,192,000 gallons

Minimum number of gallons pumped after 30 days = 24,192,000 gallons
